Journey

These games are, for the most part, about a journey.

It may be about a road trip, a travel with friends and family. (Road Trip)

Or an epic journey like Odyssey, something about a ring and a volcano, a voyage across the stars or maybe even dimensions. (Odyssey)

Or it may be about a journey not fitting to either of these two, like a voyage from Beijing to Berlin, in that case use this tag itself.
